Validating Cyber Reslience

Shift from Risk mitigation to Cyber resiliency with Tuskira

Imagine this: You’re a security leader sitting in yet another security review, staring at an ever-growing list of vulnerabilities. Your SIEM is flooded with alerts, your vulnerability scanner just dumped another 10,000 CVEs on your plate, and your compliance team is breathing down your neck about audit deadlines.

You’ve invested in the best tools like EDR, WAF, CSPM, NGFW, DLP, SIEM, etc., but something is nagging at you: Are you really secure, or just managing risk on paper?

Risk Management ≠ Cyber Resiliency

Organizations have operated under the assumption that if we find risks and patch them fast enough, we’ll stay ahead of attackers. But is that how cyber threats work anymore?

Why Risk Mitigation is Failing

  1. It takes too long. Prioritizing and remediating your risks can take 360+ days, exposing you the entire time.
  2. It requires more specialized tools. The more tools you buy, the more complex and siloed your security becomes.
  3. It never ends. Security teams are always reacting to another CVE, another zero-day, another compliance mandate.
  4. Moment in Time. Security posture is assessed at a single point, but threats evolve continuously. A vulnerability deemed low-risk today can be exploited tomorrow, leaving organizations exposed between assessments.

It seems like we’re in a never-ending game of patch management. What we know for sure, is that attackers are bypassing controls, chaining misconfigurations, and exploiting security blind spots faster than we can respond.

The Shift to Cyber Resiliency Thinking

What if we all shifted our mindset a bit? From risk detection to defense validation?

Cyber resiliency is a term we all know, and reaching that outcome consists of proving that your security controls actually hold up against modern attacks. Does it matter how many risks you’ve identified if they don’t?

What Cyber Resiliency Enablement Looks Like in Practice:

Validation over assumptions. Knowing where you’re vulnerable is not enough because you need to know if your defenses will actually stop an attack.
Optimization over inefficiency. Your security stack is already massive.  You have the right tools and instead of adding more, optimize the ones you have.
Preemptive defense over-reactive patching. Continuously test your security posture and adapt defenses before an attack happens.

Can You Prove Your Defenses Work?

Most security programs today focus on:

  • Vulnerability Management: Finding and patching CVEs
  • Detection & Response: SIEM, EDR, MDR
  • Compliance & Risk Reporting: Traditional GRC tools

These are necessary pieces of a security stack, but again, how certain are you your defense posture will withstand an attack and protect your business?

That’s why security teams should think bigger:

  • Cyber Resiliency Programs instead of just Cybersecurity Programs
  • Risk Mitigation & Validation over just Risk Detection
  • Defense Validation instead of just Security Tool Management

Your security stack is most likely great, and you have the righttools. But are those tools working together? Are they being used to their full potential? And are they being continuously tested against real-world attack scenarios? Again, cyber resiliency is an outcome of knowing that your defenses will stop an attack before it happens.

So, to ask once more: Are you certain your defenses will protect you from an attack? The answer we often hear is, “No one is.” Okay, then maybe it’s time we rethink our approach
